Gene/ral arrange-ment.-Tlie machine preferably comprises a frame X ofany suitable construction but preferably divided up so as to make itreadily transportable; also a feeding and carding mechanism A, a ropeformingfmechanism B, the wrappingl mechanism C, the crimping mechanism D(which -may be replaced by a suitable pasting mechanism as hereinafterdescribed), the severing mechanism E, and the tape mechanism F.Extending along one side of the bed of `the frame X isa main shaft 1that may be driven in any suitable manner as by fast and loose pulleys2, 2a and preferably divided and having its parts connected by a clutch3, whereby one end of themachine'may be operated independently of theother inestablishing adjustments.l lIn order that the shaft 1 may drivethe several mechanisms of the machine, it is provided with-a bevel gear4 that drives the upwardly extending shaft 5 for the feeding and cardingmechanism;`

a worm gear 6 that is adapted lto drive the v forming and conveyingtrough wheel 7 of the rope forming mechanism; an angle gear 8, adaptedto drive the pressure wheel 9, which is encountered by the ropeimmediatel)1 after entering the wrapping tube; an

angle gear 10, which drives the crimpingwheel 11 or its substitutedpaster, when em ployed: a -worm gear 12, which drives the tape Vwheel13; and a gear 14, which drives the severing mechanism E, all as willbeE hereinaftermore fully set forth.

The tobacco feeding and carding mechanism A, as best shown in Fig. 11,comprises a feeding belt 16 passing over a roller 17 and a roller 18coperating with the belt to condense the tobacco placed upon the belt asitvpasses between the rollers; also a pin roller 19 to which the tobaccois fed, and upon which it adheres, and a concave 20, supported bybearing rests 2Gb, such .as shown in dotted lines, in Fig. 11, inposition to lie closely to the belt roller at its upper, inner end toprevent tobacco adhering. to the belt and deecting, and confining thetobacco to the pin roller 19; also a stripping roller 21 having pinsupon its surface, which pick the tobacco from the roll 19. Rollers 17 18and 19 are preferably vrun at substantially equal surface speed butroller 21 is a fast roller that cards the tobacco by`its fast movement.This carding effect is increased by the provision of fixed teeth 20a onthat portion of the-concave 20, which is presented toward the roll 21.The tobacco is deposited by the roll 21 constantly and in a uniform andwell divided condition, into the throat 22 by which it is directed tothe vperipheral conveying trough 7a on the wheel 7 by which it isdelivered to the rope forming mechanism B.

The housing for the feeding and earding mechanism is constructed toprovide a dust box X, closed at top by the concave X2 and hinging coverX3, and provided atrbottom with a hinging door X* for the discharge ofdust accumulating therein.- The feeding and carding mechanism is drivenby the shaft 5 extending upwardly froin thejbevel gear 4 and provided attop with a pinion 5a meshing with a pinion 23EL on a short Worm shaft23, which drives the worm wheel 19a on the shaft of the slow pin roller19.. The latter carries a pinion 19", which lmeshes with a' broad pinion17a on the shaft of the belt roller 17, and said broad pinion 17a mesheswith and drives the pinion 181 011 the feed roll 18, which lies in adifferent plane from the pinion 19h. This arrangement of drive impartssubstantially equal surface'speed to the rolls 17, 18 and 19. The shaft23 is further'provided with a bevel pinion 23", which meshes with a likepinion 24", meshing with a pinion 21a on the fast or picking pinroll`21. This Will impart to the roll 21 a speed much faster than thatof the rolls 17, 18 and 19.

The rope forming mechanism B.-This rcomprise's the wheel 7 having theperipheral conveying trough 7, which receives the t0- bacco from thethroat 22. Immediately after being deposited in the trough 7 a, thetobacco -passes beneath the packing and driving inion 24a on a short`shaft 24, which carries at its other end, a

the trough in a uniform and continuous rope,

until Ait is delivered'to the wrapping tube 24 (Fig. 1) of the'formerand folder, which it of the wheel 7, its disposition relatively to thewrapping tube and its direction of rotation; the wrapping tube beingthus made to extend from one side of a diameter of the Wheel intangential. direction toward which the Wheel, at the point of tangent isrotating so that the tobacco rope simply follows its natural course inleaving the wheel on a tangent, as soon as it is released from thewheel. To confine the rope in the conveying trough without disturbingits texture, a tongue 25, curved substantially concentric to and adaptedto fit the trough 7a, is pivoted at 25a at its receivingend and heldinto the trough by the screw 28 at its discharge end, the desireddistance to restrict the rope to the proper dimensions prior to enteringthe wrapping tube.

By referring to Fig. 12, it will be seen that the inner face of thetongue 25 may be made flat, if desired for the greater portion of itslength and that it is preferably made with a concave inner face 25" atits discharge end, whereby the rope is rounded on its outer surface andbetter adapted to avoid resistance in entering the tube. It will also beits discharge end, extends in a straight line where the tangentialportion of the path of the rope begins so that the rope is directed intothe tube Without bending; a scraper 25c being preferably provided atthis end to release the rope from the carrier wheel.

By referring to Fig. 2, it willr be seen that the packing and drivingwheel 23 is provided With a tread 23a by which it is adapted to bearagainst and to be drivenv by the lateral iange or tread 7b of the wheel7; said wheel 23 being provided with a grove 23b between its `packingrim and its tread to receive the Wall of the conveying trough. Treads23a and 7 b, may be toothed if desired.

The for/mer and foZler.-'-This part of the arrangement (Figsklto 20)wherein the llO tobacco' meets the paper borne in by the endtion 27ahavin locking ears 27b adapted to engage with p1ns27a on the member 24and the l upwardly swinging end members 27u, 27, respectively hinged tothe fixed portin 27, so that they may be y.conveniently lifted-forinspection of the work and the part 27c1 can be detached and replacedwhen worn. The central portion 27a is con .inclined edge 24 lays thepastedvedge tol -'g st ructed with a recessi 9 to receive `an aniriharyforming wheel 9, which reduces the l thickness of the tobacco fillerrior to entering the finishing-tube 27d, Fig. 19) '(See also Figs. 1 and3) which perfects the form of the filler. The tube thus constructed,gradually tapers from a lfunnel presented to receive the tobacco rope atthe entrance end to an extension 27"'l on the finishing tube, where thepaper is folded in known manner, afte'i` which it passes through thecrimping device27. Theparts 27a, 27c and 27d providel channelsv betweentheir side walls and the walls of the trough 24, which const itute theguides for the paper in order to confine the tobacco to its channel andalso to prevent accumulation of dust on the paper preliminary toseaming. Figs. 15 and 16 show the -tube modified in aknown. manner toadapt it for forming a pasted seam, in which use, paste would be appliedat the location suggested by the dotted pasting wheel 27g, F ig. 15. Thefunnel tube 27x is supported on the base 24x by the rear 'hooks 27",engaging the pins 24, and ha`s a hinged rear section 27c as in Figs. 13and 14, but the other end is rigid and is sustained by the hook 27,engaging the pin 24". Beyond the pasting --wheel 27 g in the directionof feed is the depressing plate 24 whose colnpletethe wrapper.

The auxiliary forming wheel 9 is driven through a shaft 9b from the gear8; Athe wheel 9'being held in working position by means of the clampscrew 9c entering`the bracket 9d. Since the gear 8 is constructed asillustrated inv Fig. 9, the sha-ft 9b of wrapping tube when desired.-

the wheel 9 may be swung upwardly to permit removal of the upper portionof the The papeffeedng mechanism )V2-This comprises the lusual endlesstape 28 passing around the roller 288L at the receiving end of theforming and 'folding or wrapping device, and the driving wheel-13 drivenby the worm 'gear 12 as a ready explained and l located at the rear endof the tapes travel.

In order to increase'the friction between the belt 28 and the wheel 13,the clamping idlers 29 'are provided, which, asl shown 1n.

. Figs. 23 and 24, are mounted on acarrier 29", which is pivoted at 29",to the hanger 29, which is in turn pivoted to a lfixed point 29d; andan.v adjustingsleeve 29 having l meseta bearing against the pivote'dbearing bracket 29, and t readed on the tension shank 29K, which is'pivotally connected with the carrier 29a. Obviously by screwing theadjusting sleeve 29e on the shank 29g, the latter is drawn upwardthrough the fixed bracket 29t and thel idlers 29 are made to press morefirmly against the peripheryof the whee'113.

Tape tensioning-.In order to tension the tape 28, it is made to passbeneath a roller 30 mounted inan arm 30, which is pivoted at 30b on afixed part and provided with a tension rod 30 passing through the fixedbracket* 30d beneath which and threaded upon the rod is the adjustingnut 30".

Tape 'guida-In order to guide the tape 28 and prevent it runningunevenly in the guide provided for it and the paper in the forming andfolding tube, it is passed over a deiecting roller 31 mounted within afixed a5 bracket 31 in a manner best understood upon reference to Fig.5. 31" represents the journal for the roller. 31, which is carriedeccelitricallyby a supporting post 31, which enters the clamping bracket31 and may, e0

when said bracket is loosened, be rotated by a 'suitable tool applied tothe squared end 31d, until thatportion of the periphery of the roller,over which the tape 28 travels,

can be presented at any desired angle and at the tape thereby caused torun to one side or the other and `thus made to assume its properposition inthe forming and folding tube. Hence the roller 31, mounted asdef scribed becomes an adjusting means for the -tape'.

Tape speed adjuster.-In order to adjust the speed at which the tapetravels, the wheel 13, which drives the tape is made adjustable indiameter. To these ends, said wheel is built 1r of a central hub orspider res 13a and radial y adjustable segments 13h mounted upon therespective arms of the spider through Ithe medium'of radial tongues andgrooves 13tg as shown Vinsection, in Fig. 22, and secured thereto bymeans of slots and set screws 13; said segments being each constructedwith a rim forming section 13i v and a section of an inner tapered flawhile. the hub of the spider has threaded externally upon it a wedgingsleevevl;t that is adapted to force thesegments 13b radially outward.'It` is very' important to be able to accurately adjust the surfacetravel of the' tape and through it the paper in order to agree with therfeed of the tobacco, and considerable advantage is gained byfacilitating this adjustment since the feed of the tobacco is largelydependent upon 'its condition of moisture.

Severng cinica- In .the manufacture of cigarettes in the form of acontinuous rod,

onv acommercial scale, it is vnecessary to provide accurate and eicientsevering means capable of operating at a very high v13e, f

tra

rate of speed; also to have the cutter travel .with the cigarette rod solong as it intersects the path of the rod, in order to avoid bucklingthe rod. For these reasons, litis very desirable to have a severingdevice lof simple and durable construction. Again the v length of theindividual cigarettes cut .oif from the constantly advancing rod isdetermined by the frequency with which the severing device dips into orintersects the path of the rod; in other words, the length of rod thatispermitted to feed past the severing point before the knife intersects;hence in order to adapt' the machine to cut cigarettes of differentlength, means are provided for determining the period of the cuttingstroke relatively to the feed of the cigarette rod. This is accomplishedby simply varying the speed of the cycle of movements executed by thecutter. This in turn gives rise to the desirability of an adjustment inthe length of the throw of the cutter inthe direction of the feed of therod, since it is obvious that if the cutter is executing its cuttingmovement more slowly, it remains in the path of the rod a longer tlmeand, therefore, its throw vin the direction of the feed should beslightly longer to prevent buckling the rod. 1

' With these and other ends in view, the

severing device comprisesa frame32 mounted upon a transverse pivot l33,which adapts it to swing longitudinally of the machine, or in the lineof feed;l a cutter 34 mounted upon the frame through the medium of avertical slide 35 working Ain a bearing 36 on the frame, whereby thecutter may be drawn downward to intersect the path o f the cigarettethrough the guide tube 37, mounted upon the upper end of the frame; anda cam wheel 38 having a face groove 38a engaging a pin 35a on the slide35 to impart reciprocating movement to the slide and through it to theknife, and a peripheral groove 38b engaging a pin 32 on the frame 32 ina manner to oscillate said frame on its pivot 33 through an angle, whichwill cause the knife 34 to move with the tobacco rod during the interimof intersection.

The guide tube- 37 shown in Figs. 25 and 26 has'a bore of substantiallythe same diameter from end to end. The greater eX- terior ldiameter fora portion of the length is for the purpose of providing a suitable bodyof metal for mounting the tube.

The knife 34 is la rotary blade' having a pulley 348L that receives abelt 41 from the large wheel 42 supported by the arm 42,

angularly' adjustable concentrically with the main shaft 1 to tightenthe belt 41, and having a smaller rim 42b that receives a belt 43 rfromanother large wheel-44 that is on the Imain shaft 1. In this manner, avery Arapid rotation is imparted to the knife 34. The I upper portion35) of the slide 35 is adjustable relatively to the lower portion bymeans of a set screw 35. In this manner, the relation of the cuttingedge to the path of the cigarette may be determined to a nicety inplacing the knife in position originally and whenever it has beenreduced in diameter by regrinding. v

T o drive the cam 38, shaft l1 carries a pinion 45, which meshes with anidler 46 through which motion is transmitted to a pinion 47 carried bythe camshaft 39. In order to change the relative speed of rotation ofthe cam 38, and thereby determine thc length of cigarettes to be cutoff, the gear wheel 47 is made removable and interchangeable with gearwheels of different sizes, for

which reason'idler 46 is mounted in a slot 46a concentric with the mainshaft 1, carrying the gear. wheel' 45 with which the idler meshes. Thisadapts the idler to establish driving relation between the gear wheel 45and any size of pinion 47 that may be found desirable. The pin 32aextends through a slot 32b in the frame 32 and is clamped in position bya nut 32, against the inner and outer faces of said frame in order toraise and lower the pin relatively tothe fulcrum or pivot 33, andthereby amplify or reduce the throw of the upper end of-the frame andthe parts carried by the frame to conform to the feed of the cigaretterod during the interim of intersection of its path by the knife. ,TheVinner and outer faces against which thel pin 32a is clamped arecurvedjconcentric` with the cam shaft 39 so that the pin 32aretains itsradial relation to the cam wheel lat `whatever adjustment it is placed,and does not impairits bearing in the peripheral cam groove. To regulatethe adjustment ofthe pin 32a to a nicety, the frame carries a setv screw32d working in a fixed bearingon the frame and connected with the pinasshown.

Novel coperatz'on of different mecha,- n'isms.-Aside from the noveltyresiding in the several mechanisms perse,v different mechanisms coperatetoJ produce novel effects. Thus not-only does the feeding and cardingmechanism deposit tobacco in proper condition,l but Jbeing disposed atto correspond in width to the arcuate extent of the upper vportion ofsaid wheel upon which the tobacco will effectively deposit by gravity,and'being timed to advance the tobacco at the proper speed relatively tothe rotation of the trough wheel, it insures the proper thickness of therope, which accumulates as the wheel rotates through said arcuate space,and then permits the rope, which thus accumulates, to travel half arevolution of thewheel, where it tends to drop by gravity into'thetangential path by which it proceeds straight to Ithe forming andfolding tube. Again the tape tightener 30 not only t 115 right angles tothevtrough wheel and made ,properly determines the tension of the tape,but by its adjustment, it permits the enlargement of the tape drivingWheel without making the tape too tight or too loose; moreover itspreferred location, as shown near the angularly adjustable tape guidingWheel 31, insures a better control of the latter over the tape. ln likemanner, the tape clamping idlers 29 are radially adjustable" in order topermit ot establishing the proper driving relation between the tape andthe Wheel 13, at Whatever size the wheel 13 may be adjusted to.

The adjustment of the time or period of cutting motion not only has itseffect in determining the length of the cigarette, but it aords especialadvantage when used in connection with a` machinehaving the adjustableWheel 13, whereby the speed of the tape may be determined at vvill andthrough it the rapidity with which the cigarette rod is delivered. Againthe several'adjustments in the cutting period and in the amplitude ofthe cutter frame, bear especial relation to 25 the adjustment of thespeed of the tane aside from the Ifacility, which they oder for changingthe length of the cigarette, in that they admit of being adjusted tomaintain a constant length otcigarette when the tape is adjusted tocorrespond with the condition of the tobacco.
